NCP Industries ADORN Stone Ledgestone Series Post Stone

NCP Industries’ ADORN Post Stone offers the only mortarless solution specifically engineered for 6x6 posts with CO2-capturing concrete technology. This system wraps standard 6” x 6” posts (actual 5.5” x 5.5”) using an interlocking panel design that requires only standard fasteners—no mortar, no masonry skills, no waiting for anything to cure.

Skip it if you’re wrapping 4x4 posts without modification. The system is specifically designed for 6x6 posts; for 4x4 posts, you’ll need to shim the post to 6x6 dimensions before installation. This isn’t a universal post wrap—it’s engineered for one specific size.

Technical Specifications and Coverage

Each piece measures 9.5 inches long by 6 inches tall by 1.75 inches thick. When installed around a post, the outside dimension becomes approximately 9.5” x 9.5”. Coverage per box varies between 1.5 to 2.0 vertical linear feet, with approximately 12-16 interlocking stone pieces per box organized as sets to surround the post.

Specification	Value
Piece dimensions	9.5” L x 6” H x 1.75” D
Post compatibility	6x6 posts (actual 5.5x5.5)
Outside dimension installed	9.5” x 9.5”
Coverage per box	1.5-2.0 linear feet
Weight per box	45-55 lbs (varies by profile)
Fire rating	Class A (Non-combustible)
Material	High-strength manufactured stone (concrete) featuring CaptureCrete CO2-neutralizing technology

Color options include Buckskin, Colorado Gray, Desert Tan, Northern Gray, and Terra. The weight varies by profile, but expect to handle boxes in the 45-55 pound range—manageable for one person but easier with two when stacking multiple courses.

Installation Requirements That Actually Matter

The substrate prep requirements aren’t optional fluff—they protect your post and warranty. Treated wood posts must have a peel-and-stick rubberized asphalt membrane (like ProtectoWrap) applied before installing stone to prevent corrosion from chemicals in treated wood. Skip this step and the copper-based preservatives in treated lumber will attack your fasteners.

General exterior surfaces require a Water-Resistive Barrier (WRB), typically a 15lb felt layer over standard house wrap. This isn’t about the stone—it’s about managing moisture that gets behind any cladding system.

Fastener choice matters: corrosion-resistant screws like GRK R4 or U2 Universal, with 2 screws per Post Stone piece through the attaching flange. Don’t cheap out with drywall screws. The system depends entirely on mechanical attachment, and Montana’s freeze-thaw cycles will test every connection.

Tools required: drill/driver, level, measuring tape, wet saw (if cutting is needed), and safety glasses. Installation follows a logical sequence: prepare the post with required membrane/WRB, start at the bottom with a perfectly level first course, wrap the four pieces around the post to form an interlocking course, secure each piece with 2 screws through the flange, then stack subsequent courses interlocking with the one below until reaching desired height.

Montana-Specific Performance Advantages

The Class A fire rating (non-combustible) matters in a state where wildfire risk affects insurance and building decisions. Unlike polymer stone panels that melt, this concrete product won’t contribute fuel to a fire.

The CaptureCrete technology actively absorbs and avoids CO2 emissions during manufacturing, with each square foot capturing approximately 1.5 lbs of CO2 and the manufacturing process avoiding about 1 lb of CO2 per 21 sqft. For contractors working on LEED projects or with environmentally conscious clients, these products contribute to LEED points and carbon credit opportunities.

The mortarless system shines during Montana’s short building season. Compared to traditional mortared stone veneer, ADORN is significantly faster to install, requiring no masonry skills or drying time. It’s lighter weight than natural stone and more uniform in shape, reducing structural load and simplifying the installation process. Unlike faux polymer stone panels, ADORN uses real concrete (manufactured stone), providing better fire resistance and a more authentic feel/weight.

The Bottom Line

ADORN Post Stone solves a specific problem well—wrapping 6x6 posts with real stone appearance minus the mortar hassle. The interlocking system works, the fire rating matters for wildfire zones, and the installation speed helps contractors maximize Montana’s construction season.

The trade-offs are clear: limited to one post size without modification, requires specific substrate prep, and costs more than wrapping posts with wood or vinyl. But for projects where stone appearance and fire resistance matter—deck posts visible from the street, commercial entrances, anywhere aesthetics meet code requirements—this system delivers.

The product comes with a 30-Year Limited Warranty covering manufacturing defects when installed according to manufacturer instructions and local building codes. Finish with a matching ADORN sill or cap (sold separately), and you’ve got a complete stone post system without mixing a single batch of mortar.

Frequently Asked Questions

Q: How much area does one box of ADORN Post Stone cover?

One box of NCP Industries ADORN Post Stone covers 1.5 to 2.0 vertical linear feet of a 6x6 post. Each box contains approximately 12-16 interlocking stone pieces and weighs 45-55 pounds depending on the profile.

Q: Can I use ADORN Post Stone on 4x4 posts?

NCP Industries ADORN Post Stone is specifically designed for 6x6 posts (actual 5.5” x 5.5” dimensions). To use it on 4x4 posts, you must first shim the post to 6x6 dimensions before installation.

Q: Do I need special membrane for treated wood posts?

Yes, NCP Industries requires applying a peel-and-stick rubberized asphalt membrane like ProtectoWrap to treated wood posts before installing ADORN Post Stone. This prevents corrosion from chemicals in the treated lumber attacking your fasteners.

Q: What kind of screws should I use with ADORN Post Stone?

NCP Industries specifies corrosion-resistant screws such as GRK R4 or U2 Universal for ADORN Post Stone installation. You need 2 screws per Post Stone piece, fastened through the attaching flange into the post.

Q: Is ADORN Post Stone fire-rated for wildfire zones?

Yes, NCP Industries ADORN Post Stone carries a Class A fire rating (non-combustible). The product is made from high-strength manufactured stone (concrete), not polymer materials that can melt in fire conditions.

Q: What warranty comes with ADORN Post Stone?

NCP Industries provides a 30-Year Limited Warranty on ADORN Post Stone covering manufacturing defects when installed according to manufacturer instructions and local building codes.
